Question: How do you resolve the error in IIs that says: The request filtering module is configured to deny a request that contains a double escape sequence. The error causes the image not to be shown in IIS.
Answer: When you see this error in IIS, go to IIS and follow the steps below:
1. Click on the Server node, and in the ServerName Home Working Dashboard under IIS Section,
you will see Request Filtering
2. Double Click on it and on the right-hand side you will see "Edit Feature Settings" link, click on it.
3. On the Window that pops up, Check in the box that says "Allow double escaping"
[Note]: If this does not resolve the error, do the same when you click on the specific site node under Sites. Repeate the same steps.
4. Restart the IIS Server
5. Restart the site.
